SIST EN 300 356-12 V3.1.3:2003 is an ETSI European Standard for Integrated Services Digital Network (ISDN) signalling over Signalling System No.7, specifically ISDN User Part (ISUP) version 3 for the international interface. It specifies the stage 3 protocol procedures and switching functions for the Conference call, add-on (CONF) supplementary service, so implementers can support multi-connection calls between more than two parties. The text is based on ITU-T Recommendation Q.734, clause 1 (1993), with ETSI modifications.

What does SIST EN 300 356-12 V3.1.3:2003 specify?

SIST EN 300 356-12 V3.1.3:2003 specifies the stage 3 of the CONF supplementary service for pan-European ISDN using the ISUP protocol. In practice, that means it covers the signalling behavior and exchange functions needed to set up and support the service on the international interface.

The scope is limited to the international interconnection. It does not add protocol requirements for delivery over a non-ISDN network, and it does not define the extra requirements for the national signalling interface. The text also keeps message formats, codes, procedures and exchange actions that are marked for national use, so they can be read in the international specification.

What are the key requirements of SIST EN 300 356-12 V3.1.3:2003?

SIST EN 300 356-12 V3.1.3:2003 focuses on how the CONF supplementary service is handled in ISUP stage 3. The practical effect is that network and switch vendors must implement the signalling procedures and switching functions exactly as modified by ETSI, not as the unmodified ITU-T clause.

Stage 3 behavior

The standard defines the protocol procedures and switching functions that support the service. That is the implementation layer, so engineers use it when they build or verify the exchange behavior rather than the service description.

Service scope

The CONF supplementary service gives a user a multi-connection call, meaning simultaneous communication among more than two parties. It applies to telecommunication services carrying speech, so service planning should check that the target service is speech-based.

Network boundaries

The document applies to the international interface only. If the service is provided through a network that is not an ISDN, or if the national signalling interface needs extra behaviour, that extra behaviour must be handled outside this document.

National-use items and gateways

Items marked for national use are kept for information in the international interface specification. If a national network and an operator network support them, the international gateway exchange is expected to support both the national and international behavior where the national signalling system differs.

Reference alignment

ETSI replaced several ITU-T references with specific ETS and EN equivalents. For implementation work, this tells readers which companion version to follow for the related ISUP base, supplementary-service framework, and Q.931 signalling layer.

Annex ZA coding

Annex ZA gives coding guidance for the compatibility information in the generic notification parameter. That matters when equipment has to encode or interpret interworking information consistently.

What terms does SIST EN 300 356-12 V3.1.3:2003 define?

• Integrated Services Digital Network (ISDN) - The digital network environment for which this signalling standard is written.
• ISDN User Part (ISUP) - The part of Signalling System No.7 used for ISDN interconnection signalling.
• Conference call, add-on (CONF) - The supplementary service that enables a multi-connection call with more than two parties.
• Stage 3 - The level that defines protocol procedures and switching functions needed to support the service.
• Digital Subscriber Signalling System No. one (DSS1) - The subscriber signalling system named in the related service and protocol references.
• Protocol Implementation Conformance Statement (PICS) - A companion conformance document used to state what a product implements.
• Test Suite Structure and Test Purposes (TSS&TP) - The companion test specification that organizes conformance tests and their purposes.

Who uses SIST EN 300 356-12 V3.1.3:2003?

SIST EN 300 356-12 V3.1.3:2003 is used by ISDN switch and signalling engineers, network operators, and conformance test teams working on international ISUP interconnection. It is also relevant to buyers and quality managers checking whether equipment supports the CONF supplementary service and the related ETSI test documentation.

What changed in SIST EN 300 356-12 V3.1.3:2003 from the previous edition?

SIST EN 300 356-12 V3.1.3:2003 corresponds to the ETSI publication EN 300 356-12 V3.1.3 (1998-08). The ETSI modifications to ITU-T Recommendation Q.734, clause 1, insert a scope and normative references at the start of clause 1, replace several references with ETSI/EN versions, delete subclauses 1.5.2.1.1.9 and 1.5.2.1.1.10, and delete Figures 1-9/Q.734 and 1-10/Q.734.

What does the SIST EN 300 356-12 V3.1.3:2003 document contain?

The document contains the modified clause 1 text for the CONF supplementary service, including the scope, normative references, reference substitutions and deletions from the ITU-T source clause. It also contains Annex ZA, which gives coding guidance for compatibility information in the generic notification parameter.

For implementers, the useful content is the signalling and switching description for the international ISUP interface and the related reference map to companion standards in the EN 300 356 series. For test and assurance work, the document points readers to the companion PICS, TSS&TP, ATS and PIXIT parts for supplementary services.
